Gather up ALL the things that remind you of your ex - photos, jewelry, clothing, etc and put into a big box. Put the box in your attic or basement or store it at a friend's house. Get it out of your life. If in several months when you are through this you still want those things, they will be in the box. But otherwise you can donate the items to the salvation army. In the meantime, they will be out of your life and let you heal.
